public class CustomItemSelectedListener implements AdapterView.OnItemSelectedListener {
    private List<CardView> selectedItems;

    public CustomItemSelectedListener() {
        selectedItems = new ArrayList<>();
    }

    @Override
    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
        CardView cardView = (CardView) view;
        if (cardView.isSelected()) {
            selectedItems.add(cardView);
        } else {
            selectedItems.remove(cardView);
        }
    }

    @Override
    public void onNothingSelected(AdapterView<?> parent) {
        // Do nothing
    }

    public List<CardView> getSelectedItems() {
        return selectedItems;
    }
}

CustomItemSelectedListener listener = new CustomItemSelectedListener();
cardView.setOnItemSelectedListener(listener);
